Ukraine-Russia tensions: US deploys fighter jets to Eastern Europe

F-35 fighter jets

Russia, one of the world's superpowers, is conducting military operations in Ukraine. The attack began early Thursday, local time. The Russia-Ukraine war is considered to be the biggest conflict in Europe since World War II.

In the midst of this tension, a contingent of American state-of-the-art F-35 fighter jets has arrived in Eastern Europe. The news comes as tensions between Washington and Moscow escalate over the ongoing crisis in Ukraine.

On Thursday, Russian President Vladimir Putin launched a military operation in the Donbass region of eastern Ukraine. The United States then deployed six F-35 fighter jets to the Eastern European countries of Estonia, Lithuania and Romania.

The United States has said the planes were deployed in Eastern Europe as part of President Joe Biden's order this week to restructure troops and military equipment in Eastern Europe.

Announcing the troop deployment, President Biden said it was a defensive move, not an aggressive one. At the time, he made it clear that the United States had no intention of engaging in war with Russia

There is no end to the excitement surrounding the James Webb Space Telescope among scientists and space enthusiasts. One researcher and his team are getting the opportunity to use that telescope at the very first stage.

Dominica Wilesalek is the first to get a chance to experiment with the new telescope. He was one of the 13 teams selected to use the new super telescope in space. 

Dominica says, "If you really start practicing astronomy and better understand the tiny fraction of the night sky that you see with the naked eye, it's a completely different perception. If I am aware of that again, it will still be a thorn in my side. "

Particularly interested in the massive black hole or black hole in the center of the Dominica galaxy. When matter is swallowed, strong air radiates from that cavity. He said that the wind could help in the process of birth of stars in the galaxy, but also to stop the process.

The role of black holes in the evolution of galaxies is one of the fundamental questions of astronomy. In this context, Dominica Wilsalek said, "A comparison of the size of the massive black hole and its host galaxy shows the difference. Much like comparing the size of the moon with the money made of metal. However, during active development, massive black holes could have a huge impact on the galaxy. "

As an astronomer, Dominica wants to know how black holes affect them. Because we also live in the Milky Way galaxy.

New telescopes in space will illuminate those galaxies more accurately. For more than 1,200 billion years, their light has penetrated through space. The light radiated at a time when black holes were swallowing up more matter and emitting stronger winds. Its effects on the surrounding environment can be gauged from the information captured by the telescope. 

Dominica Wilsalek, a researcher at the University of Heidelberg, said: That means there's a spectrum behind every pixel in that image. "

The spectrum will show exactly how much gas there is in a distant galaxy. The speed of the galaxy, the direction of motion can also be known. Based on that information, it will be possible to better understand the evolutionary process of the galaxy.

Dominica will examine distant galaxies with the help of a filter wheel mounted inside the camera. It was made at the Max-Planck Institute of Astronomy in Germany. Everyone is eagerly awaiting the application of that instrument.

For 14 years this campaign had to be postponed again and again. Dominica is now waiting to gather information from there. "We have a responsibility," said Dominica. Because with the help of that information, we will be able to know what other astronomers should know. I can tell you what James Webb really can do. So very good preparation is needed. "

To reach the final position in space and to be fully active, the telescope had to open the parts step by step. No satellite has ever been launched with so many parts that can move. It took two weeks to match everything. There was no room for error. Six months after launch, the telescope has begun delivering preliminary data.

What's in this version of Android 13?

With more importance on the security and privacy of the phone, this time Google has brought Android 13. This allows phone users to easily share specific photos and videos. Other files will be protected. Apart from this, differences have also been brought in the theme icons. The new Android operating system has been named Tiramisu. This new version has amazing features for the users. According to Google, the final stable version of Android 13 may come in August. Everything that is in Android 13 ...

Photo Picker: This allows you to give any other app access to the photo of your choice. The app will not be able to access other media files at will. As a result, the privacy of the phone will increase.

WiFi facility: Apps also need permission to connect to WiFi on Android 13 supported devices.

Custom Quick Settings: Notification Quick settings will have shortcut options. As a result, by tapping there, the active status of Facebook and Instagram can be turned off.

Pre-app language: It may contain different languages ​​in the system language of the apps, so that there is no problem in understanding the code.

Android update through Play Store: Now you don't need system upgrade to get new features in Android. In other words, Android 11 or 12 users will get any picker feature play update of Android 13. The result will be easily updated.
